Sisterly Secrets Unveiled

The morning sun streamed through the heavy velvet curtains, casting a warm, golden hue over the bed where Zipp and Pipp slept.

Zipp lay flat on her back, but soon shifted to her side. As she partially opened her eyes, she saw her sister in a similar position on the opposite side of the bed. As Pipp gently raised her eyelids, her gaze fell upon Zipp, and in that instant, both of them gasped, their eyes widening in shock and terror.

They swiftly propped themselves up, clutching the sheets tightly against their bare chests for modesty and holding their heads while groaning as they began to feel the effects of their respective hangovers.

"Fuck, my head," Zipp muttered, pinching the bridge of her nose. "I drank way too much last night."

Pipp winced, "Me too. I can't remember the last time I had that much to drink."

Zipp turned to look at her sister, her eyes widening as the memories of the previous night came rushing back. "Pipp... did we...?" she started, her voice trailing off as she blushed deeply.

Pipp's cheeks turned just as red, and she nodded, looking down at her hands. "Yeah, we did," she whispered. "We did it a lot."

Zipp ran a hand through her short hair, groaning in dismay. "Aw... shit!" she cursed as she face palmed in dismay and disgust. Zipp quickly got out of bed and scrambled to find her clothes. "Alright, listen to me. We shouldn't have done this! We should not have done this!"

Pipp turned around, grabbed her bra from the floor, and began putting it on. "The incredible, mind-blowing incestuous sex, or drinking too much?"

"Both! We're sisters, Pipp! We're not supposed to... you know." Zipp said as she bit her bit, her cheeks still flushed with embarrassment.

Pipp sighed, pulling her bra straps up and adjusting the cups. "Yeah, I totally get it. I mean... we definitely don't want this to happen again..." she muttered as she found and slipped on her panties, now back to normal after being stretched out by Zipp.

"Absolutely not! No! We do not want to do this again. Never." Zipp stated firmly as she struggled to put on her pants.

"Obviously. That would be super awkward, and wrong." Pipp agreed, trying to not look flushed as she put her blouse back on.

Zipp put on her shirt and sighed. "We just made a mistake. I made a mistake."

"Hey, we were drunk. It was both our faults!" Pipp tried to assure Zipp.

"Right. And we're sisters... We can get past this..." Zipp claimed, though it sounded like she was trying to convince herself. "We'll just pretend it never happened."

Pipp nodded, buttoning up her blouse. "Exactly. We'll go back to being normal sisters. Last night was just... a blip."

"A big, naked, sweaty blip." Zipp muttered.

Pipp chuckled, trying to lighten the mood. "Well, yes, but we won't talk about it. It's like it never happened."

"Ever." Zipp added bluntly. She groaned as she covered her mouth a little. "I think I'm gonna sick..."

"Hangover or because you slept with your sister...?" Pipp inquired slowly.

"Could be either honestly... Excuse me..." Zipp said before she hurried to the bathroom to vomit.

Pipp tilted her head back and sighed. While her sister repeatedly vomited into a toilet, something she could hear even with the door closed, Pipp worked on putting on the rest of her clothes.

She glanced at the rumpled bed, the sheets tangled and stained with remnants of their night together. Her cheeks flushed at the memory, and she quickly averted her gaze, focusing instead on smoothing out her blouse.

Zipp emerged from the bathroom, pale and shaking. She leaned against the doorframe, her eyes closed as she took deep, steadying breaths. "I think I'm gonna shower," she muttered, not meeting Pipp's gaze.

Pipp nodded, biting her lip. "That... that sounds like a good idea."

Zipp pushed off from the doorframe and stumbled back towards the bathroom, her movements unsteady.

She could feel Pipp's eyes on her, but she refused to look back. She knew if she did, she'd see the same guilt and confusion reflected in her sister's gaze that she felt churning inside her own gut.

Inside, the bathroom was small and cramped, the once-white tiles now yellowed with age. Zipp turned the faucet, letting the water run until it was scalding hot. She stepped under the spray, hissing as the steam hit her skin, hoping the burn would distract her from the turmoil inside.

She scrubbed herself raw, trying to wash away the remnants of their night together.

The scent of their lovemaking still lingered, a ghostly reminder of their transgression. She lathered her body, her hands shaking as she tried to rid herself of the evidence, the memory.

After what felt like hours, she turned off the water and stepped out, wrapping herself in a towel. She hesitated before opening the door, steeling herself for the awkwardness that awaited her. She took a deep breath and stepped out, finding Pipp sitting on the edge of the bed, her head in her hands.

Pipp looked up as Zipp entered, her eyes red and puffy.

It was clear she had been crying. Zipp paused, taken aback by her sister's distress. She had expected awkwardness, certainly, but not tears.

"Pipp, what's wrong?" Zipp asked softly, her voice filled with concern. She approached the bed, sitting down beside her sister.

Pipp sniffled, wiping her eyes with the back of her hand. "I just... I can't stop thinking about last night. About what we did."

Zipp sighed, rubbing her temples. "Me neither," she admitted. "But we agreed we weren't going to talk about it. We were going to pretend it never happened."

Pipp nodded, her voice barely above a whisper. "I know. I just..." she said before her voice trailed off.

She seemed to be struggling to find the right words.

Zipp waited patiently, her heart pounding in her chest. She could see the turmoil in Pipp's eyes, the internal battle she was waging with herself.

Pipp took a deep breath, her hands twisting in her lap. "I liked it, Zipp. I liked it a lot," she confessed.

Zipp's eyes widened in surprise. She hadn't been expecting that. She had thought Pipp would feel the same guilt and shame that she did. But instead, she saw a spark of desire in her sister's eyes.

"I... I don't know what to say, Pipp," Zipp stammered, her cheeks flushing. She looked down at her hands, twisting them in her lap.

Pipp reached out, placing a gentle hand on Zipp's knee. "You don't have to say anything," she said softly. "I just needed to get that off my chest. I know it's complicated, and I know we shouldn't have done it. But I can't deny how I feel."

Zipp took a deep breath, her mind racing. She stared down at Pipp's hand on her knee. As she placed her own hand on top of hers, she could feel how warm and comforting it was. She looked up, meeting her sister's gaze. "I understand," she said, her voice barely above a whisper. "I'm just... surprised, I guess. I thought we were on the same page."

"We are!" Pipp tried to assure her. "But... you can't tell me that you don't remember feeling some kind of spark when we were... you know... Because... even though most of what happened is one big erotic blur now... I definitely remember feeling that spark when we first kissed... Do you?"

After a long moment of silence, Zipp spoke again. "...No," she claimed.

Pipp lowered her head sadly. "Oh. I see. Guess it was only me... Bet it was probably just the alcohol and nothing else..." she shrugged before standing up and walking to the door.

"Pipp..." Zipp tried to speak.

"Come on. Let's check out and get home." Pipp said without turning around as she left the room.

Zipp sighed deeply as she stared down at the floor. She hated that she had to lie to her sister, but she knew the two of them could never have a romance due to them being related.

The thought of it made her shudder.

After she took another deep breath, she followed Pipp out of the room.

The two stayed quiet for most of the taxi ride home. As much as both of them wanted to spend some time apart, they knew it would be hard due to the fact that the two of them lived in the same apartment.

So, when they arrived home, they found themselves tiptoeing around each other, trying to avoid any sort of awkward conversation or situation.

Zipp, being the more outgoing and adventurous of the two, decided to take matters into her own hands. She grabbed her skateboard from the closet and announced, "I'm going out for a while. I need some fresh air and space."

Pipp looked up from her book, her eyes meeting Zipp's. "Okay," she replied softly, a hint of sadness in her voice. "Be careful, okay?"

Zipp nodded, giving her sister a small smile.

"Always am," she said before grabbing her helmet and heading out the door. She needed to clear her head, to process everything that had happened. Plus, there was something about the rush of skating that always helped her think.

As she cruised down the sidewalk, the wind whipping through her short hair, she couldn't shake the feeling of unease that settled in her stomach. She had always been the one to take risks, to live life on the edge. But this... this was different. This was taboo. This was wrong.

She shook her head, trying to dislodge the thoughts.

She didn't want to think about it. Not now. Not ever. She focused on the road ahead, on the familiar streets of their neighborhood. She carved through the traffic, weaving in and out of cars with ease. Yet, no matter how fast she skated, she couldn't outrun the memories of the night before.

As she approached the park, she slowed down, coming to a stop at the edge of the path. She hopped off her board, tucking it under her arm as she walked towards a bench.

She sat down upon it with a sigh before burying her face in her hands.

"What is wrong with me?" Zipp asked herself. "I still can't believe I fucked my sister. What am I gonna do now...? Should I move out? Should I find my own place? Tell our Mom? No. She'd kill us! So what..."

Suddenly, her phone buzzed in her pocket. She pulled it out, her heart pounding as she saw Pipp's name flash across the screen. She hesitated before answering, her thumb hovering over the green button.

She knew she should ignore it, put some distance between them. But instead, she swiped right and brought the phone up to her ear.

"Hey, Pipp," she answered, her voice steady despite the turmoil inside her.

"Zipp, where are you?" Pipp's voice was tinged with worry. "I've been calling you for ages."

Zipp glanced around, realizing she had been so lost in thought she hadn't noticed the setting sun. "I'm at the park," she replied. "I needed some time to myself."

There was a pause before Pipp spoke again. "I understand. I... I just wanted to make sure you were okay."

"I'm fine, Pipp. Just... thinking, you know?" Zipp tried to keep her voice casual, as if she wasn't grappling with a whirlwind of emotions and questions.

"Thinking about what?" Pipp pressed, her voice soft but insistent. "About us? About last night?"

Zipp hesitated, her grip tightening on her phone. "Yeah," she admitted, her voice barely above a whisper. "That too."

Pipp sighed, and Zipp could picture her sister running a hand through her long purple hair, a habit she had when she was deep in thought. "I can't stop thinking about it either," Pipp confessed. "I know we said we wouldn't talk about it, but... I can't just pretend it never happened. Can you?"

"No." Zipp admitted. "I can't."

Pipp let out a shaky breath, as if she had been holding it in. "I'm glad it's not just me," she said, her voice barely above a whisper. "I feel so confused, Zipp. On one hand, I know this is wrong. We're sisters, for God's sake. But on the other hand... I can't deny how I feel. I can't just turn off these feelings," she confessed, her voice trembling slightly.

Zipp listened to her sister, her heart aching with a mix of guilt, confusion, and something else she couldn't quite put her finger on. She took a deep breath before speaking, "I understand, Pipp. I do. I'm feeling all sorts of messed up too. But here's the thing - we can't act on these feelings. Feelings of which I do not have, by the way..." she claimed stiffly due to it being a lie.

"R-Right. It was just... a drunken mistake that we both regret." Pipp said after a brief pause.

Zipp heard her sister's voice crack slightly when she spoke, and she felt a pang of guilt. She knew Pipp was trying to put on a brave face, but she could tell the whole situation was taking a toll on her.

"Pipp, I..." Zipp started, unsure of what to say. She wanted to comfort her sister, to tell her that everything would be okay. But she knew that would be another lie. Nothing was okay. They had crossed a line, and there was no going back.

"It's fine, Zipp," Pipp interrupted, her voice steadier now.

"I get it. We can't... we can't act on these feelings. We're sisters, and that's that." She paused, taking a deep breath. "But I still care about you, Zipp. More than anything. And I don't want this to come between us."

Zipp felt a lump form in her throat at her sister's words. She swallowed hard, trying to keep her emotions in check. "Me neither, Pipp," she managed to say. "We're in this together, right?"

"Always," Pipp replied, her voice soft but firm. "So... see you at home soon? I'm cooking dinner."

"Cool. Be home soon." Zipp promised. "Bye."

"Bye. Love you." Pipp said softly, making Zipp's heart skip it beat since it felt like those words had a different meaning now.

"Love you too." Zipp repeated before hanging up.

She stared at her phone for a moment, Pipp's words echoing in her mind. She had said it hundreds of times before, but now, it felt different. Now, it felt charged with a meaning that made her heart race and her cheeks flush.

She took a deep breath, trying to calm herself. She couldn't let this consume her. She needed to keep her head clear, to think rationally. She stood up, tucking her phone back into her pocket. She needed to skate, to lose herself in the motion, the speed.

She hopped back onto her board, pushing off with a burst of energy. She weaved through the park, her mind racing as fast as her body. She couldn't shake off the conversation with Pipp, her words echoing in her mind and refusing to be silenced no matter how hard she tried to block them out.

When she finally returned home, she was greeted by a pleasant smell.

Pipp was in the kitchen, cooking dinner. Zipp could hear the sizzle of meat and the clatter of pots and pans. She hesitated to speak, unsure of how to act, how to say. Eventually, she found the words though.

"Hey, Pipp," she called out softly, stepping into the kitchen. "Need any help in there?"

"Hey, Zipp. No, I've got it under control. Unless you want to set the table?"

"Sure thing." Zipp said, trying to keep her voice casual as she walked out the foyer and towards the kitchen.

When she entered, she was met with a sight that caused her cheeks to turn red and nearly gave her a nose bleed.

Pipp stood in front of the stove, her bare backside exposed. The only thing covering her was an apron, and that was it. Despite this, she continued to cook as if it were completely normal.

Zipp's eyes widened, her heart pounding in her chest. "Pipp, what the fuck are you doing?!" she demanded, her voice barely above a whisper.

Pipp looked over her shoulder with a puzzled look. "Huh? What do you mean?" she asked innocently. "I'm just cooking dinner."

Zipp's eyes flicked down to Pipp's bare ass, hanging out of the apron. "Pipp, you're... you're naked under that apron," she stammered, her cheeks flushing.

Pipp glanced down, as if just realizing her state of undress. "Oh, this?" she said, laughing. "Yeah, I was just feeling a bit hot. Thought I'd cool off while I cooked."

Zipp's mind raced, her heart pounding in her chest. She couldn't believe what she was seeing, what she was hearing.

Her sister, her own flesh and blood, was standing there, cooking dinner in nothing but an apron, her bare ass on full display. Zipp's mind was a whirlwind of confusion, guilt, and something else she couldn't quite put her finger on. She tried to look away, to break the spell, but her eyes were glued to Pipp's curves, her bare skin.

Pipp turned back to the stove, her hips swaying slightly as she stirred the sauce. "You know, Zipp, I've been thinking," she said casually, as if she wasn't standing there half-naked.

"W-What about...?" Zipp asked as she sat down, still flustered and struggling to look away.

She could feel her sister's eyes on her, but she refused to meet them, instead focusing on the table setting in front of her.

Pipp turned to face her sister, a playful smirk on her lips. "I've been thinking about what you said earlier, about us not being able to act on these feelings. And I think... I think maybe we've been looking at this all wrong."

Zipp finally looked up, her eyes meeting Pipp's. "What do you mean?" she asked, her voice barely above a whisper.

Pipp took a deep breath, her cheeks flushing slightly. "I mean, what if... what if we could... explore these feelings without actually acting on them? Without it being... you know, real."

"What do you mean, without it being real?" Zipp asked, her voice filled with confusion.

Pipp bit her lip, her eyes flicking down to the table before meeting Zipp's gaze again. "I mean, like... role-playing. We could pretend to be someone else, you know? Someone who isn't our sister."

Zipp stared at her sister, taken aback by her suggestion. "Role-playing?" she echoed, her voice filled with disbelief. "Pipp, that's... that's crazy. I mean, it's not like we can just pretend we're not sisters."

Pipp shrugged, turning back to the stove. "Why not? It's not like anyone else has to know. We could keep it our little secret."

Zipp hesitated, her mind racing. She knew it was a bad idea, that they were playing with fire. But there was a part of her, a dark, twisted part, that was intrigued by the idea.

She quickly shook her head. "No. No way. Even if we were blindfolded and pretending to be different people, deep down I'd still know it was you. And I cannot, will not, go down on my sister while I'm sober. No matter what. That was the agreement, remember?"

Pipp shrugged. "Ok. It's was just a thought," she claimed. "Burger's are done. Could you grab my buns?"

"What?!" Zipp responded, flustered.

"My hamburger buns." Pipp stated.

"Oh! Right. Right." Zipp nodded while mentally scolding herself. She stood up and went over to get the hamburger buns, trying hard to keep her mind out of the gutter while giving them to nearly naked sister.

As she handed Pipp the buns, their fingers brushed against each other's, sending a jolt of electricity through them. Both of them pulled back quickly.

"Fuck," Pipp muttered under her breath. "Sorry. I didn't mean to -"

"It's okay," Zipp said hurriedly, cutting her off before quickly getting back to the table.

As they sat across from one another, the meal was consumed in silence, punctuated only by the occasional uncomfortable glance. The air was heavy with tension, their eyes locked in a steady gaze that seemed to stretch on endlessly.

Pipp broke the silence first, her voice barely above a whisper. "Want a drink?"

Zipp gulped. "The last time we had a drink, things didn't turn out quite as we had hoped..." she pointed out.

"Was it really that terrible?" Pipp asked, sounding almost hurt.

The tomboy blushed, feeling like a smitten schoolgirl again. "No... It wasn't completely terrible..." she admitted.

"How much do you remember about it? I mean, clearly." Pipp inquired, interested.

"Some parts." Zipp shrugged, blushing.

Seeing this, Pipp smirked. "The best parts?"

Pipp prodded, her eyes gleaming with curiosity and something else that made Zipp's heart race.

Zipp shifted uncomfortably in her seat, feeling her cheeks grow hotter. "I remember... I remember liking it when you touched me," she admitted, her voice barely above a whisper.

Pipp's eyes widened slightly, a slow smile spreading across her face. "Oh, really?" she said, her voice taking on a sultry tone. "And where exactly did I touch you, Zipp?"

Zipp's breath hitched in her throat as she remembered Pipp's hands on her body, her mouth, her tongue.

She could feel her heart pounding in her chest, her body growing warm at the memory.

Pipp leaned in closer, her voice barely above a whisper. "Do you want me to touch you again, Zipp? Like that?"

Zipp's cheeks flushed while bit her lip, her fists clenched tightly. "Knock it off..." she whined a little.

"Sure a drink won't calm you down?" Pipp asked.

A deep sigh escaped the older sister. "Ok, fine. maybe one drink," she declared.

Of course though, not too long after that 'one drink', she had another. And so did Pipp. Eventually both of them were drunk as skunks again.

It started with casual touches, a hand on the knee, a brush of the arm. But soon, it was more. Much more.

Zipp's eyes were half-lidded as she watched Pipp's tongue dip out to lick her lips. She couldn't help but follow the movement, her own tongue darting out to wet her suddenly dry lips. She could feel the heat building between her legs, her panties growing damp. She shifted in her seat, trying to ease the ache.

Pipp noticed, her eyes flicking down to Zipp's crotch before meeting her gaze again.

"You're so fucking hot right now, Zipp," she drunkenly murmured, her voice laced with desire. "I can't help but want to touch you, to taste you."

"Ditto!" Zipp slurred. "Who cares if we're sisters? I should be allowed to fondle your tits and ass! It's perfectly fine to be curious, even when society tries to convince us otherwise!"

"Totally!" Pipp agreed. "Fuck society! Who cares if we're sisters! I want you, Zipp. I want you so fucking bad."

Pipp abruptly stood up, her chair screeching loudly against the wooden floor. She stumbled a bit, her drunkenness making her unsteady on her feet. But she didn't care. All she cared about was getting her hands on her sister.

Zipp's eyes widened as Pipp approached her, her heart pounding in her chest. She could feel the heat radiating off her sister's body, could see the raw desire in her eyes. She knew she should stop this, put an end to it before it went too far. But she couldn't.

Thanks to the alcohol, her inhibitions, common sense and morality were all long gone.

Pipp leaned forward, peering directly into Zipp's eyes while resting her hands on the arms of the chair for support. She offered Zipp a familiar glance, the same easy expression she always wore when they interacted.

Before Zipp could fully grasp the situation, Pipp's hand found its way to her thigh, her tongue was dancing in her mouth, and they were both caught up in a whirlwind of passion like a couple of exuberant teenagers.

The haunting memory of last night clung to her like a shadow, but even more impossible to dismiss was the undeniable spark and warmth she felt with the stunning girl who was utterly forbidden: her very own little sister.

It was hilarious how out of character she was acting. Not only was she doing something so taboo, but she also indulged in the very thing that caused the whole thing to happen once again. And yet, her sister was just too tempting to resist. All it took was one look for her to throw her doubts aside and dive back into this forbidden relationship.

The electricity between them was palpable, their bodies pressing together as their lips danced in a passionate tango. Zipp's hands explored Pipp's curves, her hands running up and down her sides before slipping around to grab a handful of her ample ass.

Pipp let out a moan, her hips bucking against Zipp's as she deepened the kiss. Their tongues clashed, their teeth clicked, and their breath mingled in a heated exchange. Zipp could feel Pipp's nipples hardening against her chest, could feel the wetness between her sister's legs seeping through the apron.

She broke away from the kiss, her breath ragged as she looked into Pipp's eyes. "Fuck, Pipp," she panted. "You're so damn sexy."

Pipp bit her lip. "And you're driving me crazy," she replied, her voice husky with desire. "I need you, Zipp. I need you so fucking bad."

Zipp's hands moved from Pipp's ass to her breasts, squeezing them through the apron. "These fucking tits," she groaned. "They're perfect, Pipp. Hey, let's go to my room, shall we?"

"Ok!" Pipp smiled. "So, who's carrying whom?"

"I will!" Zipp declared as she stood up. "Just don't blame me if I accidentally drop you. I mean I am super drunk and you're super heavy!"

"Hey...!" Pipp whined childishly before Zipp pulled off her apron and swept her off her feet. She smiled and wrapped her arms around Zipp as she began to carry her away bridal style.

They stumbled down the hallway, laughter echoing through the house, and crashed into walls a few times before finally making it to Zipp's room. They fell onto the bed in a tangle of limbs, their laughter turning into moans as they began to explore each other's bodies again.

Zipp's hands went straight to Pipp's breasts, squeezing and kneading them tightly. Pipp let out a moan, arching her back to press herself further into Zipp's touch. Paulina could feel her sister's nipples also becoming hard, straining against the fabric, and she couldn't wait to get her hands on them.

They both propped themselves up and knelt on the bed facing each other, lost in their kisses.

Eventually, they pulled away and smiled, devouring each other with their eyes.

"Oh, sis..." Pipp moaned.

"You're a cutie, Pipp." Zipp claimed while hiccuping.

Zipp's hands found their way to Pipp's breasts, cupping them, and kneading them like dough. Pipp let out a moan, her head tilted back, and her eyes closed. Zipp took advantage of this and leaned in, taking one of Pipp's nipples into her mouth. She sucked hard, eliciting a loud gasp from Pipp.

Pipp suddenly grabbed Zipp’s breasts over her shirt, squeezing tightly enough that Zipp recoiled and let out a startled cry.

She pulled Zipp's shirt off and held her smaller boobs in her hands, making them go up and down slowly.

Zipp's moans grew louder as Pipp's fingers pinched and rolled her nipples. She could feel her pussy throbbing, her panties soaked with her arousal.

"Fuck, Pipp," Zipp panted, her hips grinding against Pipp's thigh. "You're making me so fucking horny."

Pipp smirked, her eyes gleaming with lust. "Is that so?" she said, her voice low and sultry. "Maybe I should do something about that."

She pushed Zipp down onto the bed, her hands moving to her pants.

She unbuttoned them quickly, her fingers trembling with anticipation. Zipp lifted her hips, allowing Pipp to pull her pants off, leaving her in nothing but her soaked panties.

Pipp's eyes quickly locked with Zipp's, a wicked smirk on her lips. "You're so fucking wet, sis," she said, her voice laced with desire. "I can see it through your panties."

Zipp bit her lip, her cheeks flushing. "That's all your fault, Pipp," she said, her voice barely above a whisper. "You know... for walking around with your ass hanging out and all that."

Pipp giggled. "Yeah, I knew that would get you," she admitted. She then began to rub Zipp's panty covered crotch, causing Zipp to moan and tilt her head back.

Her fingers were firm yet gentle, applying just the right amount of pressure to make Zipp squirm with pleasure. She could feel her sister's fingers moving in circular motions, her clit throbbing with each touch.

"Fuck, Pipp," Zipp groaned, her hips bucking against Pipp's hand. "That feels so fucking good."

Pipp looked up at her sister, her eyes filled with lust. "You like that, huh?" "You like it when I touch your pussy?"

Zipp nodded, her cheeks flushing. "Yeah, I do," she admitted, her voice breathy. "I fucking love it, Pipp."

Pipp's smirk widened, her fingers moving faster, applying more pressure. "Good," she said, her voice husky. "Because I fucking love touching your pussy, sis."

Zipp bit her lip, her hips moving in time with Pipp's fingers. She could feel her orgasm building, her body tensing as the pleasure became too much to bear.

"Fuck, Pipp," she groaned. "If you keep doing that... I'm gonna come."

"If I do this?" Pipp inquired teasingly as she poked and prodded her sister's privates.

"No, please, please don't do it..." Zipp weakly begged.

Pipp grinned even wider and pulled her finger away. "Down on all fours," she ordered.

Zipp was too enamored, and of course too drunk, to say no. "Yes," she responded.

Soon enough, Zipp found herself on all fours in front of Pipp, presenting her panty-clad rear.

"You have a big butt." Pipp remarked bluntly. She also noticed how much Zipp was blushing. "Feeling a little shy about diving into this, are we?"

Zipp glanced back with a cute, shy look on her face. "I-I am, but... you said that no butt stuff would happen, you... promised me..."

Pipp grinned cheekily. "Are you sassing me? Not a good look, young lady," she lightly scolded her sister before beginning to pull her panties down to her knee pits.

"No... No Pipp..." Zipp weakly begged.

Pipp lightly gripped Zipp's hips and smiled as she stared into Zipp's ass cavern.

"Oh, Zipp, you're so fucking sexy," she murmured, her voice laced with desire.

Pipp leaned in, her breath hot on Zipp's skin. She could feel her sister's lips brushing against her ass, her tongue darting out to lick her.

She then started to squeeze Zipp's large buttocks, working them with her hands before burying her face between them and licking.

Zipp shivered as her sister started to lick and suck her anus. Pipp's tongue moved around, enjoying the flavor of Zipp's butthole. Zipp arched her back with a moan and a smile, allowing Pipp to reach further. She pushed her tongue further inside, separating Zipp's butt cheeks with her fingers as she ate her out. Zipp's body shivered with excitement as her hips moved on their own.

"Ah! Lick! Deep inside me!" Zipp encouraged her. "Eat me out, Pipp. Make me come."

Pipp's tongue was relentless, lapping at Zipp's asshole like a starving animal. She could feel her sister's body tensing, her moans growing louder.

"Fuck, Pipp," Zipp groaned. "Your tongue feels so fucking good. I'm gonna come, sis. I'm gonna come all over your face."

Pipp moaned, her tongue moving faster, her fingers digging into Zipp's hips as she continued to feast on Zipp's ass. She could feel her sister's body convulsing, her asshole clenching around her tongue.

Finally, Zipp let out a long scream as she came undone.

Her whole body convulsed and shook, her heart slammed against her chest, and her breath left her lungs as wave after wave of pleasure washed over her.

Pipp moaned, her tongue still buried deep inside Zipp's ass. She could feel her sister's muscles clenching around her, pulsing with the rhythm of her orgasm.

She continued to lick and suck, dragging out Zipp's pleasure until she was left a trembling mess.

Only then did Pipp pull back, a satisfied smirk on her face before she leaned in and gave Zipp's right butt cheek a playful little bite that made her older sister squeal. Pipp chuckled and playfully bit Zipp's rear once more.

After that, she firmly grasped a generous portion of skin just above Zipp's buttocks and delicately bit into it before releasing her grip. Zipp let out a prolonged moan, experiencing a mix of pain and ecstasy.

She could feel Pipp's teeth sinking into her flesh, a sharp, delicious pain that sent jolts of pleasure straight to her clit. She bucked her hips, pushing back against Pipp's mouth, needing more, needing everything.

Pipp chuckled, her breath hot on Zipp's skin, before she pulled back and said. "You like it when I bite you?"

Zipp could only moan in response, her body writhing with pleasure.

Pipp obliged and repeatedly marked Zipp's ass with her teeth, leaving several faint bite marks on her skin. Zipp could feel her pussy throbbing, her arousal growing with each bite. She needed Pipp to touch her, to make her come again.

She needed it more than she needed air. She began to wiggle her rump uncontrollably until Pipp chuckled, her hands moving to Zipp's hips, holding her still.

"Not so fast, sis," she said, her voice slurred yet seductive. "I'm not done with you yet."

Zipp whimpered, her body aching with need. "Please, Pipp," she begged. "I need to come again. I need you to make me come."

Zipp's voice was ragged, her breath coming in short gasps. She could feel Pipp's fingers teasing her entrance, slipping in just a little before pulling back out again. It was torture, pure and simple, and she couldn't take it anymore.

"You want me to make you come, huh? Well, I think I can manage that." Pipp said.

She slipped two fingers inside Zipp's pussy, filling her completely. Zipp let out a moan, her hips bucking as she tried to take more of Pipp's fingers inside her.

"Fuck, yes," she panted. "Just like that, Pipp. Oh god, you feel so good."

Pipp smirked, her fingers moving in and out of Zipp's pussy, her thumb rubbing against her clit. "You like that, huh? You like it when I finger fuck you?"

Zipp could only nod, her body writhing with pleasure. "Yes," she gasped. "I fucking love it. Don't stop, Pipp. Please don't stop."

Pipp chuckled, her fingers moving faster, her thumb applying more pressure.

"You're so fucking tight, Zipp," she groaned.

Zipp could feel her orgasm building, her body tensing as Pipp's fingers hit that sweet spot inside her. "I'm gonna come. I'm gonna fucking come again..."

Pipp smirked and suddenly pulled her fingers out, making Zipp groan in dismay. "Not so fast, sis," she said.

The plump yet younger sister stood up, aligned her crotch with Zipp's bottom and pressed them together before grabbing Zipp's hair and forcing her to tilt her head back. After sharing a kiss with her, Pipp spit into Zipp's open mouth and kissed her again before pulling her hips back and smacking her cheeks with her crotch.

Zipp's eyes widened as she felt the sudden impact, and she let out a surprised yelp. Pipp just smirked and arched her hips back once more, thrusting her pelvis forward until it collided with her sister's backside, producing another resounding 'SMACK.'

Pipp started a rhythm, and Zipp quickly picked it up, moving back and forth on her hands and knees, bumping her backside against her sister's groin while letting out a groan.

The smacks grew increasingly louder as Pipp continued to hump her sister until Zipp's ass turned a rosy hue, matching the blush on her facial cheeks.

Eventually, Pipp turned Zipp over til her back was on the bed. As Zipp scooted back, Pipp licked her lips hungrily and hiccuped.

"I love you sis..." she slurred before promptly pouncing on her and continuing their second drunken sexual escapade.
